Qt does not handle the ACTION_POINTER_UP event on android

 static void tabletEvent(JNIEnv */*env*/, jobject /*thiz*/, jint /*winId*/, jint deviceId, jlong time, jint action,
        jint pointerType, jint buttonState, jfloat x, jfloat y, jfloat pressure)
    {
        QPointF globalPosF(x, y);
        QPoint globalPos((int)x, (int)y);
        QWindow *tlw = topLevelWindowAt(globalPos);
        QPointF localPos = tlw ? (globalPosF - tlw->position()) : globalPosF;
        // when action == ACTION_UP (1) it's a release; otherwise we say which button is pressed
        Qt::MouseButtons buttons = Qt::NoButton;



        switch (action) {
        case 1:     // ACTION_UP
        case 212:   // stylus release while side-button held on Galaxy Note 4
            buttons = Qt::NoButton;
            break;
        default:    // action is press or drag
            if (buttonState == 0)
                buttons = Qt::LeftButton;
            else // 2 means RightButton
                buttons = Qt::MouseButtons(buttonState);
            break;
        }

        QWindowSystemInterface::handleTabletEvent(tlw, ulong(time),
            localPos, globalPosF, QTabletEvent::Stylus, pointerType,
            buttons, pressure, 0, 0, 0., 0., 0, deviceId, Qt::NoModifier);

    }

 int actionType = event.getAction();
  if( actionType  == 6 ) Hanlde the ACTION_POINTER_UP
   {
      actionType  = 1;//Mark the ACTION_POINTER_UP as ACTION_UP 
   }
 tabletEvent(id, event.getDeviceId(), event.getEventTime(), actionType , pointerType,
                event.getButtonState(), event.getX(), event.getY(), event.getPressure());
